"The Jamaicans first formed in 1967 as the Cool Shakes. By the time the year was over, they'd updated their line up from a trio to a quartet, changed their name to the Jamaicans and took 'Ba Ba Boom' to first place in that year's Island Festival Song Contest. Soon after, the cut (backed by Tommy McCook & The Supsersonics) was issued on the Treasure Isle imprint to instant classic status. On the flip, it's Twilight Zone, a reverb drenched proto-dub instrumental version of the song."
